Read full descriptionHide full description
The GrindCare App allows you to visualize grinding or clenching activity detected by the BUTLER® GrindCare® device during sleep and track improvements over time. You can also enter observations in the diary section to identify key behavioral or circumstantial triggers. In the morning, you can transfer the previous night’s data from the GrindCare device to the app. To do so, please refer to the instruction manual of BUTLER GrindCare device and open the app to establish a connection. The data will be automatically transferred, and you will be able to browse the app at your convenience during the day. On the home screen, you will find an overview of detected grinding and clenching from the most recently transferred night’s data. The bars indicate when and how often the GrindCare device detected grinding or clenching; the number on the top right indicates the total number of detected grinds or clenches for this particular night. Using the diary function, you can select a smiley emoticon corresponding to how you felt upon waking up. You can also add observations regarding any specific life circumstances or events that you may later be able to correlate with your data in order to identify your primary grinding or clenching triggers. The app also has a history tab where you can review the progress of your nightly grinding or clenching, along with how you felt on each corresponding morning to track improvements. You can also access the more detailed data and observations from a specific night in the past.

100% on your iPhone — your audio never leaves the device. Bruxa records the night and lets you hear it back: the whole recording on a sound timeline, or just the moments it ranked highest. You decide what they were. Nothing is uploaded, there is no account, and there is no subscription. WHAT BRUXA DOES • Records locally overnight with a visible recording heartbeat • Plays the whole night back, so a quiet recording is never a dead end • Ranks the night's own moments and lets you play and judge each one • Tap 'Sounded like grinding' to keep a moment, or 'Not grinding' to drop it out of the list • Tracks optional jaw check-ins separately from sleep • Flags partial recordings instead of calling them quiet nights • Exports a Dentist Report PDF and CSV with PRO • Previews your Dentist Report on the morning after a complete night WHAT BRUXA WILL NOT DO Bruxa does not count teeth grinding, score your night, or grade how severe it was. Detecting grinding from a phone microphone across a bedroom is not something it can do reliably enough to put a number on, and it no longer pretends otherwise — so a quiet list is not evidence that nothing happened, and Bruxa says so on the screen rather than in the small print. What it is genuinely good for is hearing your own night and taking a real recording to your dentist. YOUR DENTIST REPORT, AND WHAT IS IN IT Only the moments you listened to and confirmed yourself, the jaw check-ins you logged, and the notes you wrote — plus the dates and lengths of your recordings. Nothing the app concluded goes into it. PRIVATE BY DESIGN No account, analytics, ads, cloud audio, or third-party tracking. Audio, analysis and reports stay on your iPhone. Delete all local data at any time. ONE PAYMENT Recording, whole-night playback, the ranked moments, corrections, jaw check-ins and your seven most recent complete nights are free. PRO unlocks full history, the complete clip library, your notes across every night and the Dentist Report — one purchase, not a subscription. No trial, no renewal, nothing to cancel. Restore Purchases is in the app. Bruxa is for wellness and awareness only. It is not a medical device and does not diagnose, screen for, treat, cure, or prevent bruxism or any dental or medical condition. If you have jaw pain, tooth wear, or concerns, talk to your dentist.

Verdict
The clearest difference is in-app purchases: GrindCare® app at none against Bruxa's 2. GrindCare® app also leads on iOS requirement (11.0 vs 17.0). Bruxa's advantage is update cadence (every 9 days vs every 24 months). On price, ads and device support there is nothing between them.
